This is an idea from W. Edwards Deming, one of the most influential productivity experts of all time. Continually work to improve everything you do and every part of yourself. You’ll find that the people in life that are always working to improve are the ones who have massive success, both in relationships and in life. Get rid of this idea that someday you’ll “arrive”, that you’ll be the perfect person and you won’t have any room to improve. Be open to growth and never ending improvement.
